Some readers of this blog might not be aware of the wonderful service VOIPBuster offers on their webpage. Simply enter the number of the phone you would like to call, and the number of the phone you want to call from and Voipbuster will call them both. This works for international calls to landlines in over 30 countries, and mobiles in the US. Some of my friends have reported that the calls used to have a time limit of 15 minutes, but this no longer appears to be the case.

As far as I am aware this is the easiest way to make free calls between two landlines. (I’m not actually aware of any service that does anything similar. Please let me know if I’m missing one).
